Often, "the" unit square refers specifically to the square in the Cartesian plane with corners at (0, 0), (1, 0), (0, 1), and (1, 1). ==In the real plane== In a Cartesian coordinate system with coordinates (''x'', ''y'') the unit square is defined as the square consisting of the points where both ''x'' and ''y'' lie in a closed unit interval from 0 to 1 on their respective axes. That is, the unit square is the Cartesian product  × , where denotes the closed unit interval. It is not known whether any point in the plane is a rational distance from all four vertices of the unit square.〔Guy, Richard K. ''Unsolved Problems in Number Theory'', Vol. 1, Springer-Verlag, 2nd ed. 1991, 181-185.〕 However, no such point is on an edge of the square.〔Barbara, Roy.
